摘要： A method and apparatus for protecting digital content in a digital rights management (DRM) system. The method of re-importing a second content file, which was imported from a first content file, as a third content file, includes determining whether to allow the re-importing of the second content file based on a difference between a current usage bind of the content determined in an import process and an original usage bind of the content and changing a usage bind of the content from the current usage bind to the original usage bind based on the result of determination. Therefore, when the usage bind of content, which had to be a domain bound, was inevitably determined to be a device bound due to a situation at the time of a content import process, the content can be freely used in the domain bound, which is the original usage bind of the content, according to usage constraints information (UCI) of the content.

摘要： A method and apparatus for managing digital content, which can detect the leakage of an encryption key when the encryption key used for encrypting the digital content is leaked or cracked. When the encrypted digital content is decrypted by an illegal device, a module linked with the encrypted digital content is automatically driven and a digital content managing apparatus is then notified that the encrypted digital content has been decrypted by the illegal device such that the digital content managing apparatus can change the encryption key. Thus, it is possible to prevent the digital content from being continuously leaked due to the use of the same encryption key for encrypting subsequent digital content.
